  • Place the seedling in the light and at the right temperature, around 18-20 °.

Penstemon maintenance

Maintaining the penstemon is very easy when properly installed. Besides a few waterings, you won't have to worry about it or much.

In winter, there is no need to cut the foliage that protects the penstemon from frost. The ideal is to cover it with a thick mulch of dead leaves to protect it from the cold.

Pensetmon is resistant to negative temperatures ranging from -5 ° to -15 ° depending on the variety.

  • Remove wilted flowers from penstemons without cutting entire stems to encourage new blooms.
  • In case of strong heat or prolonged drought, do not hesitate to water the foot penstemon in the evening.
  • Mulching at the base often helps keep the soil cool and avoids a lot of watering.
